Inside My Head

Is it wise enough to say That I'm better off without you Is it cool enough to fake Cause all that I've been thinking is about you And all that I've been doing's without you Is it you inside my head Is it you inside who says That I've become someone else On and on my mind keeps saying This is not what I believe in This is where it ends And on and on my mind's messed up That is why it never stops Alone again, I'm alone again Is it you inside my head Is it you inside who says That I've become someone else Is it you inside my head Is it you inside who says That I've become someone else I didn't know that you're coming right through inside my head I didn't know that you're breaking right through inside my head I didn't know that you're coming right through I didn't know that you're coming right through I didn't know, I didn't know How could I know? Tell me, Is it you inside my head Is it you inside who says Is it you inside my head?
